This invention relates to boiler battles and particularly to transverse or cross baffles for grouped boiler tubes.

One of the primary objects of my invention is the provision of a transverse baflle for grouped boiler tubes which is of simple construction, easy to install and easy to take down. 7 I

Another object of my invention is the provision of a transverse baflie for boiler tube banks of such character that only a smallportion of the baflle need be taken down in making tube replacements.

Another object of my invention is the provision of a tiled transverse baflie for boiler tube banks.

How the foregoing, together with such other objectsand advantages as may hereinafter appeaiy'or aieincidentto my invention, are realized is illustrated in preferred form in the accompanying drawings, wherein Fig. 1 is a moreor less diagrammatic sectional elevation of the main parts of a vertical tube boiler illustrating an application of my improved baflie.

Fig. 2 is an enlarged plan section'of a portion of the middle bank of tubes of the boiler, the section being taken on the line 22 of Fig; 1 and just above the cross or transverse baffle.

Fig. 3 is a. front view of Fig. 2, and A Fig. 4 is an end view of Fig. 3 looking toward the right.

The portion of the boiler illustrated in Fig. 1 comprises a lower mud drum 5, a pair of upper steam and water drums 6 and 7, a front bank of tubes 8 connecting the mud drum to the front upper drum 6, a second or middle bank of tubes 9' also connecting the drums 5 and 6, and a rear bank of tubes 10 connecting the drum 5 with the upper drum 7.

A baffle 11 is located at the front of the middle bank 9 and extends upwardly from the lower drum 5 to a point short of the upper drum 6, at which point is located the cross or transverse baflle 12 which willbe described in detail hereinafter. Other baffling is provided for the boiler as indicated at 13, 14, 15 and 16. The gases from the combustion chamber pass upwardly over the tubes of of angle irons.

the front bank 8, across thetub'es of the middle bank) above the baflie 12 into the space between the middle and'rear banks and from thence pass" downwardly over and amongst the portion of the middle bank located below the baflle 12 and finally pass upwardly over and amongst the tubes of the rear bank.

Referring now more particularly to Figs. 2, 3 and 4, it will be seen that the grouped tubes of thebank 9'are arranged in a Pinrality of spaced rows 17, 18, 19, 20, andso on, and that the b'aflie 12Iis constructed of a plurality of tile members and supports therefor, the particular arrangement of which is as follows: Taking,1for example, the two a-djac'ent rows"'of"tubes 19 and 20, itwill be noted that a pluralityof split tiles each comprisingtwo parts 21 and 22 are located in I the spacebetween therows Each tile partis'provided with grooves or sockets 23 adapt edto fitthe tubes [so that displacementor shifting of thetiles laterally is prevented;

As these grooves are substantially semi-circa hr, the tile parts so fit the tubes that no space,

otherthan that needed for ease of assembly and for contraction and expansion purposes, is left between adjacent tubes of the rows.

In order to support the. tiles I have provided the members 24 in the spaces between rows which, in this instance, are in the form ported from tubes ofthe rows as by means of the securing meansor U-bolts 25 which are readily detachable. As shown in the drawings, each row of tubes is provided with two tube grooves and others, for example,

parts 21a and 22a, ashaving three tube grooves. g r

The row of tiles 26 between the row of tubes 17 and the furnace wall 27 is supported by plates 28 laid upon the angle iron 24 of The angle irons are supthe row of tubes 17. The tiles of this row are placed as the wall 27 is installed.

From the foregoing it will be seen that I have provided a very simple tile baflle which can be easily installed and taken down. Among other advantages tube replacements may be made by only removing a few of the tiles which are located adjacent the tube or tubes to be replaced and without disturbing the balance of the bafile. To remove the tiles one part thereof is slid up along the tubes to clear the other part, which other part may then be removed.

I claim 1. In combination, boiler tubes arranged in grouped spaced vertical rows, angle irons located in the spaces between said rows and extending crosswise of the tubes, U bolts engaging tubes of the rows and one of the flanges of the angle irons for clamping the angle irons in position, the other flanges of the angle irons constituting shelves in the spaces between the rows of tubes, and a plurality of split tiles resting on said shelves.

2. In combination, boiler tubes arranged in grouped spaced vertical rows, angle irons located in the spaces between said rows and extending crosswise of the tubes, U bolts engaging tnbes of the rows and one of the flanges of the angle irons for clamping the angle irons in position, the other flanges of the angle irons constituting shelves in the spaces between the rows of tubes, and a plurality of split tiles resting on said shelves, said split tiles having sockets fitting the tubes.

In testimony whereof I have hereunto sign-ed my name.
